Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To provide an active type noise reduction device for which a frequency characteristic is not required to set previously and by which a noise can be effectively canceled even if a frequency characteristic is varied with time. SOLUTION: A silencing order selecting section 14 selects a frequency component having the order in which a noise level is high among frequency components being N times (= order) as much as a frequency of explosion of an engine. Concretely, a microphone signal M and a signal (Y.C) multiplying a driving signal Y and a transmission characteristic C together are inputted to an adder 14a, and a noise D (=M-Y.C) at a microphone setting position is obtained by subtracting the latter from the former. And frequency analysis about this noise D is performed by a frequency analyzing section 14b. A selecting section 14c selects a frequency component having the order exceeding the prescribed sound pressure level among peaks of each order frequency component after frequency analysis, and outputs it to a driving signal calculating section 16.

Abstract: PURPOSE:To close the route for leakage of gases from the brick joints of a tap hole by previously directing the tip of a nozzle for blowing pulverized coal of a tuyere near the upper part of the tap hole where the leakage of gases is vigorous toward the lower part of the furnace and blowing heat resistant fine powder together with an inert gas from this nozzle during operation. CONSTITUTION:The tuyere 3 near the upper part of the tap hole 1 where the leakage of gases is vigorous is closed by tapping hole clay or mud 3, etc., at the time of banking of the blast furnace to shut off blasting at the time of a blast furnace operation and the temp. near the tuyere 2 is controlled to about <=1800 deg.C. The supply of the nozzle 4 for blowing the pulverized coal from the tuyere 2 is then interrupted and the tip of the nozzle 4 is previously directed toward the lower part of the furnace. The ceramics powder which is previously adjusted in grain size constitution and has about >=1800 deg.C heat resistant temp. is blown together with the inert gas from the nozzle 4 when the leakage of the gases from the tap hole turns vigorous during the operation in this state. Gaseous flow 52 in which the ceramics powder is suspended, therefore, arrives easily near at the route 7 for leakage of the gases from the tap hole and collide against a bent part 71 at a fairly high temp. and welds this part, thus closing the route 7 for leakage of the gases.
